Automatic shutdown problem, help? 20

First: Clear the CMOS first, restore the factory value, see if the CMOS is set to the CPU shutdown temperature is set too low, try to change the power supply, it may be caused by the power supply quality is not up to par, aging, the power is too small, and the common power is insufficient.

Second, check the heat dissipation of the system, see if the CPU fan turns, three: see if your motherboard is short-circuited with **, it is possible that a small screw or something was lost in it when installing, or the motherboard capacitor has a burst of pulp, four: if it is not good, change the memory,

1.The power cord is not plugged in most likely.

2.The problem with the power supply is not enough power.

3.There is a gray wipe on the memory module.

4.Poisoning: Anti-virus or reinstallation system.

I have a friend who also had this problem. It turned out that the mouse was broken. You can try to unplug the mouse and turn it on. If this is the case, you can try to repair the mouse or replace it with a new one.

Poisoning. Or the system is not installed. Or maybe there's something wrong with the hardware... There are many reasons for this. Only one by one.

There's a problem with the shutdown button, the power button, and the motherboard components, so ask them to check it carefully.

I guess I broke the internal hardware, so go to the repair station to check it.

Recently, some netizens have reported that the computer will automatically shut down, and it is definitely not a system problem, here to share with you the possible reasons and solutions for the automatic shutdown of the computer! I hope it will be a reference for you to solve the problem!

1.There may be a problem with the BIOS settings, enter the BIOS to restore the default settings or take out the motherboard's battery, reverse the buckle discharge, and wait for 5 minutes to reverse install it. Purpose:

It is the default value of the BIOS settings to restore the default value, and the phenomenon of automatic reboot or shutdown of the BIOS cooling preset is excluded.

2.If the computer automatically shuts down when using a certain application software, the automatic shutdown fault may be caused by the program software, and the program software can be uninstalled.

3.Then check the power supply, the power supply is poor, aging or too small, can not meet the power supply needs of the computer accessories, you can replace the high-power and high-quality power supply, if troubleshooting, it is the automatic shutdown fault caused by the power supply.

4.Then use the elimination method to check the memory, graphics card, CPU, CPU fan, motherboard, etc.

5.Check the memory, the memory quality is not up to standard, poor heat dissipation, overclocking, mixing of different brands of memory, and the CAS value setting is too low, etc., can cause the computer to shut down automatically, use the test memory, and adjust the memory parameters in the BIOS accordingly.

6.Check the motherboard, the motherboard aging, capacitor failure or bursting, the motherboard power pins, the motherboard and the chassis backplate short-circuit, etc. can cause automatic shutdown, you can take the motherboard out of the chassis to check or test, then check whether the CPU fan rotation and CPU temperature is normal, and then check whether the bottom of the CPU fan heatsink silicone is dry, if it is dry, clean the silicone on the CPU fan, and then re-coat the good silicone. If the fan is not normal, replace the CPU fan.

7.It may be that playing a large game causes the CPU to overheat, and the CPU fan does not dissipate well and causes the computer to shut down automatically. If so, and automatic shutdown failures often occur, it is recommended to replace a high-quality CPU cooling fan with high speed, whether the silica gel at the bottom of the fan heatsink is dry, if it is dry, clean the silicone on the CPU fan, and then re-coat the good silicone.

If it is an automatic shutdown caused by game software, please uninstall and reinstall it.

8.The power supply system is unstable, which can also cause the occurrence of automatic shutdown faults, and a UPS backup power supply with voltage stabilization function can be considered.

9.Cleaning method: It is a method of troubleshooting by cleaning the dust of the parts in the computer host.

Dust is one of the factors that can also cause computer automatic shutdown failures, dust can cause parts aging, pin oxidation, poor contact and short circuit and other failures. For these faults caused by dust, it is generally more effective to use the cleaning method.

The power goes off after reading the strip "Did the machine restart or did the machine turn off directly?"

If it is rebooted, it is most likely your system problem, or hard disk problem.

If it is directly turned off, it may be a problem with the power supply of the case.

Turn the console on.

Put the inside. Fan clean.

That's it. System automatic relationships.

It's because of the fan.

Too much dust. The CPU temperature is too high.

So it shuts down automatically.

I've encountered this situation twice, if your computer is not poisoned, it is recommended that you first check whether the settings are faulty to restart, generally the fault is on the motherboard, you can use the detection card to check it I hope it can help you

Reinstall the C disk (no impact on other disks, do not delete other disks) buy a rainforest wood wind plate (10 yuan) into the machine, restart, press 1, there is a (it is clearly written with prompts), one key to install the machine and then he will install it himself, automatically restart after installation, and take out the disk when restarting it is OK. (Other disks have no effect) after installing the next 360 patch.

Word by word...

Overheating 2Virus.

3.Software Conflicts.

4.Scheduled tasks.

5.System files are maliciously corrupted or lost.

6.Memory.

The reason for the automatic shutdown of the machine.

Answer: The automatic shutdown of the computer is mainly caused by the following reasons:

1.Poor heat dissipation. Due to the influence of weather temperature or the insufficient number of revolutions of the CPU fan, the system overheats, which will lead to the automatic shutdown of the computer, it is recommended to check whether the system temperature is normal.

2.Memory reasons. When the contact between the memory and the motherboard socket is loose, it may also cause the computer to shut down automatically, it is recommended to check whether the memory is plugged into the motherboard.

3.Power issues. The lack of power supply is also an important factor in causing the computer to automatically shut down, but from this configuration, the possibility of this problem is very small.

4.Software factors. Computer shutdowns caused by viruses or Trojan horses also abound, especially the recent epidemic of shockwaves, which can cause the system to reboot and shut down. If you are using Windows

2000 or Windows

XP system, it is recommended that you use antivirus software to patch the blaster in time, and the general problem can be solved.

1. Causes of the virus.

Second, the problem of hardware. For example, the power supply.

3. Software problems. For example, CPU temperature measurement monitoring software.

4. System file loss and misoperation.

5. Hackers attack you.

The specific solution is to redo the system, which can be excluded; If it's still dead, it's a hardware problem.

If the computer is poisoned, or someone has artificially added a shutdown command, quickly enter shutdown -a in this window to cancel the shutdown.

at the command prompt.

shutdown -s -t xx

xx is the shutdown delay time seconds; xx can be 00, instant shutdown.

Sometimes Windows prompts shutdown after n minutes, but it is actually the time you set) at 10:00 shutdown -s (the time in between is the time to shut down, followed by the shutdown command) at 10:00 shutdown.

shutdown -a (cancel shutdown, restart, log out, etc.) Description: The s of the command refers to the meaning of shutdown, replace s with r, and shutdown becomes restart. In the same way, replacing S with L will turn shutdown into logout.

System files are corrupted!

The system automatically scans, and the results are saved in: Files.

Familiarize yourself with the system will, open the file and see what system files are damaged! Get to work.

Or to put it simply, just install the new system! USB flash drive boot, install, or ghost.
